Cant play any downloaded tracks?

I download a track and it automatically shows up on nl2, but when i click play, it will start to load and then quickly come up with a message showing that some files cannot be found. What am i doing wrong?

The track uploaded itself may not have all of the files included within it, which is the track creator's fault and not yours.

Oh alright, i will try and download some other ones and see if they work. Thanks.
